Tank

The Great Wall Motor Tank 400 represents a key step in the evolution of China’s rugged SUV segment, bridging the gap between traditional off-road capability and modern electrification. Positioned between the smaller Tank 300 and the more luxurious Tank 500, the Tank 400 has rapidly evolved since its debut, introducing new powertrains, trim levels, and technologies in just a few years.

From its concept unveiling in 2021 to its expanding lineup through 2026, the Tank 400 has become one of the most versatile models in the Tank brand. This article provides a comprehensive look at its evolution, including production years, trims, engineering developments, and future outlook.
